It does a heck of a LOT of measurements, although typically most purchasers will in all probability only use the SWR function. Pros, This doodabber does a heck of a lot. It is very comprehensive for such a dinky little package. As stated, most will be using the SWR meter function. Which it does admirably. But it also shows Smith charts, and shows a lot more that I don't yet understand fully and yet more I don't understand at all. I'm sure in time all will become clear as mud... So the colloquialism goes. Cons... Do NOT expect a manual! It comes with a list of menu functions. And if your an amateur Amateur radio enthusiast, you will likely NOT understand a single dang thing. I most certainly did not. It has a qr code to a extensive online manual which for the vast majority of the time, is well translated, but can be a little hard to follow (especially for the beginner, YouTube WILL be your friend in this). It NEEDS to be calibrated for every use. Which is a little time consuming. But worthwhile for it's utility. and you absolutely WILL NEED adapters for ANY kind of antenna plug (PL259, N type, BNC, and any other.) It is set up for SMA Type plugs. it comes with what you see which is two extensions cables, both are female to female SMA, A male/male connector and three calibration caps (OPEN, SHORT and LOAD, DO NOT LOSE THESE! they are required for calibration!) A few usb cables (C type for charging and a C to C cable). And finally a wee lil stylus and a 'guitar pick' style doodabber. These are obviously for screen interaction. Build quality: it's a sensitive lil gadget. lightweight, and a little 'plasticky'. But it's well enough made to do what it's intended to do and be robust enough. Although a degree of care should be taken when transporting it. I keep mine in it's box which has sufficed adequately thus far until I get a better option, perhaps a small pelican case. Overall: This gadget does what you will need it to do (meshtastic users, I'm looking at you!) And significantly more besides. I can certainly promise at least 75% of end user's will not utlilise its entire arsenal of tricks. It's compact and very portable. And frankly I'm a little smitten with it. One cannot help but adore a well created and executed piece of kit. especially one as delightfully complicated as this one. 10/10 will measure SWR again. Review: Good for checking antenna - Works great I use it mainly for checking SWR. Plenty of Youtube videos online to show you how it works. ## Features - Upgraded Nanovna-H HW3.7: SeeSii Nanovna-H Vector Network Analyzer is developed by Hugen. With the latest 3.7 version,9KHz-1.5GHz measure range,2.8 inch LCD touchscreen, mini and portable design. This Antenna Analyzer is provides outstanding vector network measurement capabilities and perfect for evaluating antenna resonance and SWR. It is a very mini handy & smart analyzer for electronics engineers, amateur radio operators, or radio diy amateurs - Improved Frequency Algorithm: The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 1.5GHz. The metal shield is designed to reduce the external interference and improve the measurement accuracy. The 50K-300MHz frequency range of the si5351 direct output provides better than 70dB of dynamics, The extended 300M-900MHz band provides better than 60dB of dynamics, and the 900M-1.5GHz band is better than 40dB of dynamics. The default firmware main function for vector network analyzer is used for antenna performance measurement - Multi TX/RX Function: The default firmware is mainly used for antenna performance measurement. The TX/RX method can measure the complete S11/S21 parameters (need to manually replace the transceiver port wiring) - Android Phone & PC Software Control: The nanovna analyzer uses PC software NanoVNASaver, it can connect to a NanoVNA and extracts the data for display on a computer for saving to Touchstone files. We can export Touchstone (snp) files for various radio design and simulation software through PC software. We can export Touchstone (snp) files for various radio design and simulation software through PC software. In addition, the VNA supports USB-C to USB-C lines, more convenient to connect to mobile phones. Compatible with most Android phones that support screen mirroring (not compatible with iPhone) - BUILT-IN MICRO-SD PORT & TIME DISPLAY: The latest antenna analyzer with a MicroSD card port, so you can save field test data or screens to a MicroSD card at any time, supporting up to 32GB memory card. (Not included in the package).In addition, different from the old version of NanoVNAs, the date and time can be customized, which is convenient for you to further record and save data. The default firmware main function is used for antenna performance measurement - Abundant Accessories: Comes with 1x NanoVNA-H host, 2x 30cm SMA Male to Male RG174 RF Cables, 1x SMA Female to Female Connector, 1x SMA SHORT, OPEN & LOAD simple calibration kit, 1x USB Type-C Data Cable, 1x USB-C to USB-C Cable, 1x Lanyard, and 1x Touch Plectrum. All the accessories are packaged in a sophisticated box. This is a great VNA analyzer for your use or as a gift for a friend ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08132DJLS | | Batteries | 1 Lithium Ion batteries required.

But there is a resulting decrease in performance. It’s a free update if you so choose. Wayne N4EYZ **Q: What connection type does the battery charger use?** A: This is an add-on to the other answers that may prevent damage. Quote from specs. on this product page: "maximum charging current 0.8A" In other words, this may get damaged if more than a 1 amp USB charger is used. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A fabulous, if complex device. *by F***S on 24 February 2024* This little machine is fantastic.

Plenty of Youtube videos online to show you how it works. ### ⭐⭐⭐⭐⭐ Fantastic device - what every amateur radio operator needs. *by E***C on 6 February 2024* Works great for measuring SWR and other things. Don't bother with trying to understand the menu on its own touch screen. Just download 'NanoVNASaver' for Windows and use via a USB connection to the PC. This app is almost self-explanatory in its operation. At the time of writing, github doesn't have the Windows files, but I found a copy from another source on the web. ## Frequently Bought Together - SEESII Nanovna-H Vector Network Analyzer,Upgraded HW3.6 10KHz-1.5GHz MF HF VHF UHF Antenna Analyzer, Measuring S Parameters, Voltage Standing Wave Ratio,Phase,Delay,Smith Chart,Support Data Storage - DHT Electronics Handheld Antenna Cable SMA Male to UHF SO-239 Female Connectors 6'' Pack of 2 for Amplifier - onelinkmore SMA to UHF RF Coaxial Extension Converter CB Connector kit SMA PL259 SO239 VHF Crimp Coax Adapter for Ham Radio Antenna Walkie Talkie Radio Pack of 4 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/300503105-nanovna-h-vector-network-analyzer-upgraded-hw3-7-9khz-1](https://www.desertcart.sg/products/300503105-nanovna-h-vector-network-analyzer-upgraded-hw3-7-9khz-1) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-05-19*
